Product details
Overview
JANS1N6124US/TR from Microsemi (now Microchip) is a hermetically sealed, military-grade 15 V Zener diode in a DO-213AA (GLASS) package, rated for 500 mW power dissipation, ±5% voltage tolerance, and operating across –65°C to +175°C. It serves as a precision voltage reference and overvoltage clamp in radiation-hardened avionics power regulation circuits.
For engineers reviewing the JANS1N6124US/TR datasheet, JANS1N6124US/TR pinout, JANS1N6124US/TR application, or JANS1N6124US/TR equivalent, key selection criteria include Zener voltage accuracy, total power derating above +75°C, MIL-PRF-19500/422 qualification status, and glass-package hermeticity verification per MIL-STD-750 Method 1071.
Technical Context
This device operates in reverse breakdown mode with a nominal Zener voltage of 15.0 V at 10 mA test current and exhibits a dynamic impedance of ≤20 Ω at 10 mA. Its temperature coefficient is +0.08 %/°C, enabling stable reference performance across extended thermal ranges.
MIL-PRF-19500/422 compliance ensures screening for burn-in, thermal shock, and steady-state life testing. The DO-213AA glass package provides hermetic sealing without internal wire bonds, supporting high-reliability operation in vacuum and high-humidity environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.0 V ±5% at IZ = 10 mA - defines clamping threshold for overvoltage protection in 12–15 V rail monitoring |
| Power Dissipation (PZM) | 500 mW at TA = 25°C - requires linear derating to zero at +175°C per MIL-PRF-19500 limits |
| Zener Impedance (ZZT) | ≤20 Ω at IZ = 10 mA - ensures minimal output voltage shift under load transients |
| Temperature Coefficient | +0.08 %/°C - enables predictable VZ drift compensation in wide-temperature avionics designs |
| Operating Temperature | –65°C to +175°C - qualified for use in engine-mounted control units and space-grade power supplies |
| Hermeticity Test | MIL-STD-750 Method 1071 - confirms leak rate <1×10−8 atm·cc/sec He, critical for long-term reliability in sealed modules |
Pinout & Package
DO-213AA (GLASS) package: axial-lead, hermetically sealed glass body with no exposed die attach or bond wires; leads are tinned copper alloy, suitable for solder reflow and wave processes per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / cathode reference ground node | Connected to system ground when used as shunt regulator; polarity must be observed to avoid forward conduction during normal operation |
| Cathode | Zener breakdown terminal / regulated output node | Provides stable 15 V reference when reverse-biased; connects to input rail via current-limiting resistor |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/422 Qualified | Full QML-V screening including lot acceptance tests, burn-in, and life testing - eliminates need for external reliability qualification |
| Hermetic Glass Package | DO-213AA construction with helium leak rate <1×10−8 atm·cc/sec - prevents moisture ingress and corrosion in 20+ year field deployments |
| Wide-Temperature Operation | Rated from –65°C to +175°C with defined VZ drift - supports direct mounting on high-temp power converters without thermal isolation |
| Stable Dynamic Impedance | ZZT ≤20 Ω at 10 mA - maintains reference accuracy under varying load currents in analog sensor signal chains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6124US | Same Zener voltage and package, but screened to JANTXV level (not QML-V); higher failure rate allowance per MIL-PRF-19500/422 | Approved for non-critical subsystems where full QML-V is not mandated | Select JANTXV1N6124US only when cost sensitivity outweighs mission-critical reliability requirements |
| 1N6124US | Commercial-grade version; no MIL screening, no hermeticity test, rated only to +150°C | Limited to ground-based industrial equipment with benign environments | Not acceptable for aerospace deployment; use only in non-military, non-safety-critical designs |
Compared with JANTXV1N6124US and 1N6124US, the JANS1N6124US/TR provides verified QML-V qualification, guaranteed hermeticity, and extended temperature capability - essential for flight-critical voltage reference integrity where single-point failures are unacceptable.

FAQ
What is the Zener voltage tolerance specification for JANS1N6124US/TR?
The JANS1N6124US/TR has a Zener voltage tolerance of ±5% at 10 mA test current, meaning its actual breakdown voltage falls between 14.25 V and 15.75 V. This tolerance is verified per MIL-PRF-19500/422 lot acceptance testing and applies across the full –65°C to +175°C operating range. The JANS1N6124US/TR maintains this specification under all qualified screening conditions.
Is JANS1N6124US/TR compatible with lead-free reflow soldering processes?
Yes, the JANS1N6124US/TR uses tinned copper alloy leads qualified for lead-free reflow per MIL-STD-202 Method 210. Its DO-213AA glass package withstands peak temperatures up to 260°C for 10 seconds without hermeticity loss or parameter shift. The JANS1N6124US/TR is fully compatible with standard JEDEC J-STD-020-compliant reflow profiles.
Does JANS1N6124US/TR require derating above ambient temperature?
Yes, the JANS1N6124US/TR must be linearly derated from 500 mW at 25°C to 0 mW at +175°C, per MIL-PRF-19500/422 requirements. Derating begins at +75°C, with maximum power reduced by 3.33 mW/°C. This ensures safe operation and long-term stability of the JANS1N6124US/TR in high-temperature avionics enclosures.
How is hermeticity verified for JANS1N6124US/TR?
Each lot of JANS1N6124US/TR undergoes helium mass spectrometer leak testing per MIL-STD-750 Method 1071, with a pass criterion of leak rate <1×10−8 atm·cc/sec. This verification is documented in the manufacturer's QPL report and applies to every unit shipped. The JANS1N6124US/TR's hermetic seal is integral to its 20+ year field reliability in sealed aerospace modules.
Can JANS1N6124US/TR be used as a replacement for commercial 1N6124 diodes?
No - the JANS1N6124US/TR is not a drop-in replacement for commercial 1N6124 variants due to stricter screening, extended temperature rating, and mandatory hermeticity testing. While electrically similar, the JANS1N6124US/TR requires different qualification documentation and layout allowances for thermal management. Substituting the JANS1N6124US/TR into a commercial design invalidates the original qualification unless re-verified.
